' The present invention relates to cotton condensersand moreyespecial ly to improved means for removing dust, dirt, lIlOtQSfilIlCl other extraneous matter from the cotton.

An important feature of the invention is to provide means for preventing it is introduced into the condenser from falling through 1 the condenser; screen drum and mixing with the cotton after ithas once been t separated therefrom. j

1 A further object istoprovidea cylindrical screen drum with a series of plates which extend inwardlydrom upon theplates, andis deflected towards the ends ofthe drum whereit 'is withdrawnfrom the casing by the siphonic action of the air tion with the accompanying passing through the exhaust duct in the casing.

wardlyinelined bars positioned adjacent the uppersurface of thehatforming drums for receiving the cotton lint as falls from the i b cylindrical drum to separate the trash, motes,

and other foreign material from the cotton "prior to its delivery to the batforming drums.

i Further ohjectsand advantages of the invention will become apparent from the following description, when taken in conjuncclaims. s

Within the casing is mounted revoluble cylindrical drum 12 thatis peripherally enclosedby the screen 13 and has its end 14(Fig52) dust exhaust ducts; 1:5 and 16 which extend Referring *thidifiiving which like UNITED STATES P'ATENTVOFFICE nitrous. orfsannnromofiirnxas,nssrenon 2mgAimnnsoiv,,(:Lrur'roita a A JOINT srrocx nssocIA'rIoNor TEXAS i 1 igure13 is a detailedperspective view of i I so asto align with thespaced air and fromithe top of the casing. pfIhe-mesh of h -scre n 131 sufi e y fine e gh to prevent the a passage of cotton fibers leaf trash and other large foreign substances, but

The inner end of each plate 17 may be bent upwardly asat 21 to providethe trough 22 so that the air and dust passing through the screen 13 impinges .the samezis prevented from falling through the bottom of the: drum and mixing with the cotton lint after the latterhaspassed over so" againstthesides 19 and 20 of thesubstanltlally plough-shaped plate 17 and is deflected to the ends ofthe drum where it is drawn the drum l2 andjconducted to the bottomof 190 the casing. As the dust laden'air discharged against and through the drum 12 travels at a much higher velocity than the drum itself, the plates 17 oifer a resistance which deflects the dust and air to each end of the drum adjacent the periphery thereof so that it may be discharged through the exhaust ducts 15 and 16 in the manner as indicated by the arrows in Figures 1 and 2.

Positioned in the bottom of the casing 10 are a pair of batforming drums 23, which receive the cotton lint as it falls from the drum 12. In order to remove dust and leaf trash entrained with the cotton prior to its delivery to the batforming drums 23, there is positioned in the casing adjacent one of these drums a fender grid 24:, which is secured to the casing by the strap 26. The grid 24 preferablycomprises aseries of downwardly inclined spaced bars 27 which is in the path of the cotton lint asit leaves the drum 12 so as to receive the same and acts to remove the dust and leaf'trash from the cotton before it is delivered to the batformin'g drums 23. The space between the bars 27 allows the dust and trash to fall therethrough' into a discharge chamber 28, hav ing an opening 29 that is closed by a door 30 topermit the removal of the trash from the casing. A fender 31 secured to the insideof the casing adjacent the other of the batforming drums 23 guides the'cotton that might pile up'inthe casing towards the space fo'rmed'between the batformingdrums. It willbe seen that the cottonlint is directed to the batformingdrums by the bars 27 and the fender31 and after the 'lint'has passed the drums 23,-it is compressed and fed through a pair of oppositely rotating corrugated condenser rolls 32, which discharges the cotton into a suitable baling instrumentality not shown; Access may be had to the batforming drums and fender grid-through the 'door 33 in the front of the casing.

It is'to be understood that the form of invention herewith shown and described is merely illustrative ofa preferred embodiment and that such changes as fall within the purview of one skilled in the art maybe made without departing from'the-spirit -of the invention and scope of the appended claims. 1
